Seems to be bugged atm, http://public-crest-sisi.testeveonline.com/market/types/17738/ is the uri needed to get the machariel (random item), but all the uris provided by the endpoints have it as /types/, not/market/types/

I remember you mentioning having to change this, but right now, it's giving URIs that don't work.

Indeed.

I find it awkward that you have to go through the OAuth user authentication flow to access data that is not at all character/user related. OAuth has the client credential flow for this case, which would remove all these unnecessary steps for market order data and if I understand correctly all data that will fall under the publicData scope.

Yes, and we use it internally but don't have it setup for third-party developers yet.

Few questions,


  1. will final version require OAuth or will it be public CREST stuff?
  2. what is expected release timeframe for this market API?

Any last chance for location and solar system ids (and volume entered)? After all, you already have that data - just add "id": to those elements.

If I want to work with marketing data I should still ask for Authed Crest?
If that's the case, could you give it to (on SiSi)

That part, about creating/registering the app I figured out, but if I get the following message

{"message": "Authentication scope needed", "key": "authNeeded", "exceptionType": "UnauthorizedError"}

then that's because its not there yet?

talking about this example

GET /market/10000002/orders/buy/?type=https://api-sisi.testeveonline.com/types/683/ HTTP/1.1
Host: https://api-sisi.testeveonline.com
Authorization: Bearer jKVB8oaN9qboU5kQG4sWSoWxzSUaFkQaUyeisy8jWU3apRfYSgYsKpZGNbLh41xXEzuy-NDBX1FohEdEadaukQ2
Accept: application/vnd.ccp.eve.MarketOrderCollection-v1+json

It's just copy/pasted from the article, it ain't mine ;)


And no, that's not the bearer I used.Blink

When you sent the request over to the login server, did you fill in the scope? (you probably didn't)

Woo! CSM XI!

Thanks Steve, that was it.
I missed out reading this

Initially you follow the same flow as the normal SSO auth with these differences:

1. On your call to /oauth/authorize, set your scope to "publicData"
2. On your call to /oauth/token, you now get a refresh_token in the response
3. On future calls to /oauth/token, you can use the refresh token by changing the grant_type to "refresh_token", and send the token in a "refresh_token" variable rather than a "code"
So instead of this:
POST https://sisilogin.testeveonline.com/oauth/token

grant_type=authorization_code&code=xxx

You do this:
POST https://sisilogin.testeveonline.com/oauth/token

grant_type=refresh_token&refresh_token=yyy

4. When accessing the CREST resource, just include your "Authorization: Bearer $access_token" header

Super happy about this! One quick question: what is the "right" way to get the system that a buy/sell order is in? Obviously I can just parse the station name string (assuming it continues to be the case that systems never contain a space in their name...), but that feels rather wrong and un-RESTy

For now, parsing out the location id from the href, then looking it up in the SDE for the station, works.

It's far from an ideal situation.

Did anyone get an answer about volume entered? Been asked several times, don't recall seeing any response.

It's not functionally equivalent to the in-game market export to file, or to the cache scraping it's supposed to replace, without it.

I got an out of band reply that it will re-appear in the next 1-2 releases.
